Application filed March 9, 1901. Serial No. 50,482. (No model.)

To @ZZ whom t may concern.:

Be it known that l, HENRY H. ROBERTS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in W'indows, and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a window, the object being to provide a device whereby the sashes and glass can be cleaned on both sides from the inside of the building and in which neither the appearance of the sash-frame nor construction of the sashes is changed; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

in the accompanying drawings, illustrating my invention, Figure l is an inside elevation, partly in section, of a window constructed in accordance with my invention. Fig. 2 is a transverse section of same on the line 2 2 of Fig. l. Fig. 3 is a detail section on the line 3 3 of Fig. 2.

As before stated, the main object of myinvention is to provide a window in which the sashes can be easily turned to the inside of the building and the glass cleaned on both sides.

Further obccts of in i invention are first to avoid the use of any fixtures or mechanism which will change the appearance of the window either internally or externally; second, to so arrange the parts of the windowframe as to enable the sashes to be operated for washing in the way now common, thus giving the operator the choice of either method, and, third, to so arrange the operating parts as to offer no obstacle to the movements of the sash-weights or sashes and to malte the operating parts easily accessible for purposes of repair.

To these ends my window consists of the frame A, provided with the usual guides B and C, in which the sashes D andE move, the latter being counterbalanced by the sashweights F the usual manner. One of the inner walls or jambe of said frame A is cut through laterally, preferably on a diagonal .movement in said well.

line G, and the lower piece H thereof made removable. Said piece H exceeds both the sashes in length and is held in place in alinement with the upper rigid portion of said inner wall by means of a spring I, mounted in the sash-weight well J, said spring bearing against the rear wall of said well and being secured thereto in'any suitable manner. The said spring I is preferably made of wire bent to forman oblong, and said oblong is longitudinally bent to a curve. Said oblong spring is secured between the ends of its long sides to the rear wall of said well J, so that its short sides bear against said removable member H. This spring takes up very little room and does not in any part lie in the path of the sashweights, thus leaving the latter perfectly free The blind stop K on said side of said window-frame A is also cut through on a slant between its ends and the lower portion made removable, being held in place by a screw L and by the Outer sill M. Said blind stop K is rabbeted on its inner face to form a shoulder, against which said member H bears when at the forward limit of its movement. By iirst removing said blind stop K and then forcing said member H inward against the action of said spring and then upward until its lower end passes the upper face of said sill the said member H can readily be removed.

lf it is desired to remove either sash in order to clean it and its glass eXteriorly, it is nec'- essary only to slightly raise the lower sash and then press it against the member H, thereby moving the latter inwardly until the opposite side of the sash has left its guide. The sash is then swung inwardly, as indicated in dotted lines in Fig. 2. After cleaning the lower sash the latter is raised without returning same to its guides, and the upper sash may then be lowered and removed in a similar manner.

A window made in accordance with my invention is just as weather-tight as the ordinary window, has the same appearance, and constitutes the least possible change from the usual construction.

l claim as my invention-e l. In a window, the combination with a frame having guides, of sashes movable in IOO said guides, a movable section in one of said guides, a blind stop, a removable section therein having a shoulder against which said movable section of said guide is adapted to bear and by which the latter is held against removal, and a spring engaging said movable section and adapted to hold same normally in engagement with said shoulder on said blind stop.

2. In a Window, the combination With a Window-frame having guides, of sashes movable in said guides, one of said guides being composed partially of a movable member, means for holding said movable member normally in position comprising stops and a spring engaging said member and holding same normally in engagement With said stops.

8. In a Window, the combination with a Window-frame having guides, of sashes movable in said guides, counterweights Connected With said sashes and movable in welis in said frame, a movable section in one of said guides, stops for limiting the movement of said section in one direction, a spring mounted in said Well and engaging said section to hold same normally in engagement with said stops, said spring being adapted to form a hollow quadrangle in vertical elevation and afford free movement to said counterweights through the
